х=18/2
х=9
cестра собрала 9,а брат нашёл на 7 больше значит 16(9+7)

Answer 2

Calculating the Number of Mushrooms Found by the Brother

To solve this problem, we can use algebra to represent the relationship between the number of mushrooms found by the brother and the number found by the sister.

Let's denote: - x as the number of mushrooms found by the sister. - x + 7 as the number of mushrooms found by the brother.

The total number of mushrooms found is 25, so we can create the equation: x + (x + 7) = 25

Solving the Equation

By solving the equation, we can find the value of x and then calculate the number of mushrooms found by the brother.

x + (x + 7) = 25 2x + 7 = 25 2x = 25 - 7 2x = 18 x = 9

So, the sister found 9 mushrooms, and the brother found: x + 7 = 9 + 7 = 16

Therefore, the brother found 16 mushrooms.
